Sega must have some seriously big holes in the security surrounding its Sonic The Hedgehog 4: Episode 1 development. We’ve already seen footage of Splash Hill Zone Act 1 leak in April, but Sega promptly had it removed from YouTube. Now another seven minutes of footage has appeared, this time from Mad Gear Zone Act 2.

For the moment it is available to watch on YouTube, but the description says to watch quickly as the Sega take-down request will come into force sooner rather than later.

As well as giving you a good idea of the gameplay we also get to see the Super Sonic transformation for the first time.
